Well my grand prize is time extension token. Since I've already got 8 and have never used even one, I'm not going to bother.
My rug prize is purple circles and as far as I can tell this will be my last set to complete so I'll play until I get those.
And since it seems I have everything else that is offered I may not be doing them for awhile. Which is fine, I hate having to worry about it so often when the events start lol

I got Black Grand Piano (FINALLY!!!), and pink circle rugs, which are the last ones I need from the original set. Not crazy about the minor prizes (gingerbread door and cukoo clock), but I have to take them to get to the prizes I really want.

I'm also on my last set of rugs (!!) and have a time extension token for the grand prize. I'm hoping once we've unlocked all the rugs maybe we will get to unlock items from the mystery box shop. 1 free yellow modern stool was the third milestone prize (I can't find it, though ) but I wish we could unlock those things instead of just getting one for free. If instead of unlocking items from the mystery box shop we just get one set of rugs or something else we already have I'm only going to be doing these events up to the second monument resources.

I got 1 yellow stool too and took forever to find it but finally found it in the outdoor furniture tab. I kinda wish I didn't bother wasting my resources to get just one stool.

Ah! Thank you! Mine says "yellow Modern Stool" but it's showing up black. Is yours also showing as black?

Yup, mines black too. I tried to duplicate it though, and couldn't. I couldn't find it in my home store either. I did however see that I have black steel tables available to purchase. I don't remember unlocking that item. Either there's a switch a roo or I unlocked it unknownly on a mystery box.

I do too! It's just weird because it's actually black and not that complete black that happens with a texture glitch. So they've coded for a black stool. Now I wonder if the color is wrong or the name.
